Dear Mr. John, I am Neha one of your research students at Cambridge university. I am writing this letter for thanking you for your knowledge, wisdom and support that you provide during my academic year. The reason why I am leaving the course in the middle is that last Saturday, my mother had accident while she was going to market. Unfortunately, a car hit my mother as the breaks of car were failed which leads to imbalance of car and my mother's right arm was broken during this incident. Therefore, I decided to leave the course because I want to take care of my mother. Moreover, I learned various things during this course. First of all, the concepts and ideas added in this course were extremely practical that helped me in acquiring good score in my first semester. Most importantly, this course saves money as all the information and study material is available on the internet as the load of carrying books become less. Lastly, the period I devoted to this course helped me in enhancing my communication skills as well creativity level. Thanks again for imparting knowledge as well as your time and consideration. Yours faithfully, Neha Jain
